The Office of Land Quality’s Defense Environmental Restoration Program works in cooperation with the U.S. Environmental Protection Agency to oversee and assist the U.S. Department of Defense in the investigation and cleanup of active, closing, or formerly used Indiana military installations at which hazardous substances and/or petroleum products were used, stored, or disposed of during past operations. The goal of the program is to protect human health and the environment and promote economic redevelopment through the same investigation and cleanup process as sites in the federal Superfund program.
